Neogenin-1 distinguishes between myeloid-biased and balanced Hoxb5+ mouse long-term hematopoietic stem cells

Project description:Hematopoietic stem cells (HSCs) self-renew and generate all blood cells. Recent studies with single-cell transplants and lineage tracing suggest that adult HSCs are diverse in their reconstitution and lineage potentials. However, prospective isolation of these subpopulations has remained challenging. Here, we identify Neogenin-1 (NEO1) as a unique surface marker on a fraction of mouse HSCs labeled with Hoxb5, a specific reporter of long-term HSCs (LT-HSCs). We show that NEO1+Hoxb5+ LT-HSCs expand with age and respond to myeloablative stress in young mice, while NEO1–Hoxb5+ LT-HSCs exhibit no significant change in number. Furthermore, NEO1+Hoxb5+ LT-HSCs are more often in the G2/S cell cycle phase compared to NEO1–Hoxb5+ LT-HSCs in both young and old bone marrow. Upon serial transplantation, NEO1+Hoxb5+ LT-HSCs exhibit myeloid-biased differentiation and reduced reconstitution, while NEO1–Hoxb5+ LT-HSCs are lineage-balanced and stably reconstitute recipients. Gene expression analysis reveals erythroid and myeloid priming in the NEO1+ fraction and association of quiescence and self-renewal-related transcription factors with NEO1− LT-HSCs. Finally, transplanted NEO1+Hoxb5+ LT-HSCs rarely generate NEO1–Hoxb5+ LT-HSCs, while NEO1–Hoxb5+ LT-HSCs repopulate both LT-HSC fractions. This supports a model in which dormant, balanced, NEO1–Hoxb5+ LT-HSCs can hierarchically precede active, myeloid-biased NEO1+Hoxb5+ LT-HSCs.

Mapping AT1R biased signaling using proximity-labeling and proteomics identifies diverse actions of biased agonists

Project description:Angiotensin II type 1 receptors (AT1Rs) are one of the most widely studied G protein-coupled receptors. To fully appreciate the diversity in cellular signaling profiles activated by AT1R transducer-biased ligands, we utilized peroxidase-catalyzed proximity labeling to capture proteins in close proximity to AT1Rs in response to six different ligands: Angiotensin II (full agonist), S1I8 (partial agonist), TRV055 and TRV056 (G protein-biased agonists), TRV026 and TRV027 (β-arrestin biased agonists) at 90s, 10min, and 60min after stimulation. We systematically analyzed the kinetics of AT1R trafficking and determined that distinct ligands lead AT1R to different cellular compartments for downstream signaling activation and receptor degradation/recycling. Distinct proximity labelling of proteins from a number of functional classes, including GTPases, adaptor proteins, and kinases were activated by different ligands suggesting unique signaling and physiological roles of the AT1R. Ligands within the same class, i.e. either G protein-biased or -arrestin-biased, shared high similarity in their labelling profiles. Comparison between ligand classes revealed distinct signaling activation such as greater labeling by G protein biased ligands on ESCRT-0 complex proteins that act as sorting machinery for ubiquitinated proteins. Our study provides a comprehensive analysis of AT1R receptor trafficking kinetics and signaling activation profiles induced by distinct classes of ligands.

Sex-biased gene expression

Project description:Investigatation into how genes with sex-differential expression profiles are distributed among the chromosomes in Drosophila. Assayed the expression of 14,142 predicted transcripts in competitive hybridizations and found a dramatic underrepresentation of X-chromosome genes showing high relative expression in male. This is the first report of sex-biased expression of the full (predicted) genome. Findings indicate that there is significant sex-biased expression, especially in gonads. Genes showing sex-biased gene expression profiles are likely to have sex-biased functions. Keywords: other

Humans PBMCs: Balanced constitution vs. Phlegm-dampness constitution

Project description:We investigated the expression profiles of lncRNAs and mRNAs in peripheral blood mononuclear cells (PBMCs) from subjects with 13 Phlegm-dampness constitution (PDC) and nine balanced Balanced constitution (BC). The differentially expressed lncRNAs (DElncRNAs) and mRNAs (DEmRNAs) were identified by the “limma” method. Goal was to determine whether long non-coding RNAs (lncRNAs) play a regulatory role in metabolic disease in subjects with PDC.
